Browsing OpenPCS 7 hierarchy

After startup, the connector browses the OpenPCS 7 address space in order to acquire the OpenPCS 7 information model. The scope of the initial browse can be limited by listing a set of comma separated NodeIds from where the browse-calls start. In other words, the initial browse will be applied onto the listed set of NodeIds (see the "Root NodeIds" section under Add data sources to PI Connector for Siemens SIMATIC PCS 7) and all their child objects.

Note: The connector assumes that the desired information model is stored within the "SIMATIC S7 Protocol Suite" node and considers it the root node for building the PI AF hierarchy. If such a node cannot be found, the connector is unable to continue and stops. The result is that even if the OPC UA specification is generic, the connector can only be used with OPC UA server for OpenPCS 7.
